After you have developed the IP addressing scheme for the customer, you should document it by site and by network within the site. A standard convention should be set for addressing important hosts on the network. This addressing scheme should be kept consistent throughout the entire network. By creating addressing maps, you can get a snapshot of the network. Creating physical maps of the network helps you troubleshoot the network.
| Lab Activity
| This lab will help prepare for the Case Study. In this lab you will be given some basic requirements for a small LAN that spans multiple buildings. Your focus is on the physical topology and Data link layer components. The goal is to replace an aging 10BASE2 thinnet Ethernet network with current technology Ethernet switches and cabling based on structured cabling standards and the extended star topology.
